(54) Loading ramp


(57) The improvement consists in providing the drive means (2,2A) of the loading ramp (1) with a DC electric motor (28) at a very low voltage, said motor is powered by an accumulator battery (24) associated to a battery charger (23) which can be connected to the 220 V power grid. In this way the loading ramp (1) can be driven independently of the presence of the power grid voltage and the electric system (9, 9A) is more economical since it does not require the expensive protective means needed for the corresponding electric systems which work with 380 V current.
